The first topological acoustic transistor

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...

Determining when a material becomes 'glassy'

Is it in a liquid phase or a 'glassy' phase? This question has been the subject of intense debate as physicists try to understand the behavior of so-called 'active matter'—a relatively new type of matter where particles use ...

Exotic quantum particles—less magnetic field required

Exotic quantum particles and phenomena are like the world's most daring elite athletes. Like the free solo climbers who scale impossibly steep cliff faces without a rope or harness, only the most extreme conditions will entice ...

Resolving the puzzles of graphene superconductivity

A single layer of carbon atoms arranged in a honeycomb lattice makes up the promising nanomaterial called graphene. Research on a setup of three sheets of graphene stacked on top of one another so that their lattices are ...

DNA transcription speeds, a function of collective modes driven by DNA supercoiling

A team of physicists working at the intersection of theory and experiment are shedding new light on the "teamwork" of molecular motors—called RNA polymerases (RNAPs)—that mediate DNA transcription. During transcription, the ...

Predicting high temperature Bose-Einstein condensation of excitons

National University of Singapore researchers have predicted that an exotic state of matter known as a Bose-Einstein condensate can exist at relatively high temperatures (around 50 K to 100 K) in systems comprising organic ...

Scientists document the presence of quantum spin liquids, a never-before-seen state of matter

In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers.

Magnons vs electrons: A new spin on computer processing

In 1965, Gordon Moore of Intel predicted that microprocessors would double in speed and capacity every couple of years. This prediction, now known as "Moore's Law," has with some modification in 1975 been reliably prophetic ...
